To all' who/a 'it may'comzem:

Be 1t known that we, THERON L. -KNAW and CLAYTON O. HARTING, citizens of the United States, and residents of Woodstock,

. declare that the ollowinv in the county of 1McHenry and State of Illinois, have invented certain new and useful' Improvements in Column-Stop Mechanism for Type-VVriters; and we do hereby is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to an improved tabulating or column stop mechanism for -typewriting machines designed to effect the release of the carriage froni the control of the usual letterspacing devices and' permit the, carriage to move, under the action of its actuating` spring, to a predetermined point or points, at which the movementl of the carriage is arrested, for the pur ose of printing a series of items or num ers in one or more vertical lines or columns upon f the sheet.

The invention4 relates more particularly to that class of column sto devices-in which the-carriage is provide with one or more adjustable'sto s which are mounted, and are longitudina ly adjustable, "u ona longitudinal member of the carriage rame and which are adapted to `operate in connection with a key-actuated sto -member which is movable into and out o the path of the stop or stops upon the carriage.I

The invention is herein shownas applied to a typewriting machine of the kind knownas thefOliver machine, but the features constituting the invention may be applied to machines of other kinds.

The invention consists in the mattersl hereinafter set forth and pointed out in the ap ended claims. I n

lshowing parts of the carriage and the stop-y Vmachine. Fig. 9 is a perspective view of the key-lever by which said stop-lever is 10 is a view in central vertical section of a typewriting machine provided withthe shift-frame and apercarriage illustratedin the preceding gures.

As shown in said drawings, A (Fig. 10) in'- dicates the base-frame of .a typewriting machine, andl indicates the frame by which the paper-carriage is immediately supported and which has shifting movement backwardl and forwardl on said base-frame and w ich is herein-cal ed the shift-frame The paper-carriage has endwise or letterspace movement on said shift-frame and said s ift-trame has backward and forward move- -ment on the paper-carriage 'to provide for shifting the aten in such manner as to bring the paper in position for receiving impressions from twoor more types upon each type-bar 'of the machine. Fig. 10 of the accompanying drawings illustrates the arts mounted on the base-frame A and whic l are not directly concerned with the. resent invention, said" parts bein one ofp the t pebars Bfthe key-levers one of Whicv is shown as connected with the type-bar'B by a link b, the' universal bai- D and one of its supporting arms 11,' a rock-shaft E through which the shift-frame 1 is moved or actuated and which, is provided with an upwardly eX- tending arm e connected with the shift-frame by a iink el, aspacin keygF, one ofthe spacing-keylevers, )Can a 'link f1 by which motion is transmitted fram the spacing-key to the universal bar D.' Sad shift-frame is 'shown in saidl" l1() .as provided with a rigidly connect said end plates.

bar D by means of an upright rod H1. The parts above described correspond with the similar parts heretofore employed in what is known as the Oliver typewriting machine. Said shift-frame is provided with front and rear horizontal guide rods 2 and 8, extending transversely of the machine, on which travel the supporting rollers 4 and 5 of the carriage during the endwise or letter-space movement of the carriage. 'l he frame of said carriage, as shown, consists of end lates 6 and 7 and forward'and rear longitu inal frame bars or members 8 and 9 which extend between and 1() indicates the paper roller or platen of the carriage which is mounted on the end plates 6 and 7, in the usual manner. 'lhe said longitudinal front frame member 8 of the paper carriage constitutes the rack-bar thereof and is provided on its front edge with a series of ratchet teeth 11 which are engaged by a gear pinion 12 mounted on the upper end of an upright shaft 13 mountedon the forward part of the shift-frame. Said shaft 13 has, at its'lower end, an escape wheel 14 which is part of the escape mechanism which is operated by .the universal bar of the machine and by which is controlled the endwise or letter-space l movement of the carriage under the action of the carriage actuating spring. rihe escape wheel shaft 13 has a bearing at its lower end in a forwardly rojecting'arm 15 on the lower part of the shi t-frame and at its upper end engages a bearing block 16 (Fig. 3) which is adapted to slide horizontally in a guide slot formed in the upper end ofl a bracket 17,

which'is attached to and rojects forwardly from the shift-frame. ri e sliding movement of the bearing block 16 in the said bracket 17 permits the gear pinion 12 to be moved or shifted forwardly and backwardly into andv out of engagement with the ratchet teeth IV11 and said 'block is held at the inward limit of its movement by an eXpansively acting coiled'. sprin 18 applied between the outer face of sai block and the outer endof the slot in the bracket 17'.

19 indicates the release bar of a carriage which is arranged horizontally above the frame bar 8 and adapted to slide thereon in a horizontal plane. Said release bar is proy vided with oblique slots 21 engaged by studs `2O which rise from said frame bar 8.

release bar is held at therearward limit of Said its movement by a coiled spring 22 and is o 'erated to shift the same forward against t el action Lof said spring 22 by means of an endwise sliding trip-rod 23 arranged longitudinally at the left-hand end of a carriage, and adapted to act upon the left-hand end of the release bar in such manner as to throw the same forwardly and forward the left when pressure is appliedto the outer end of said trip-rod. A, pivoted lever 24 is also located at the right-hand e'nd of the carriage I and is adapted to also act upon the release bar to throw the same forward against the action of the spring 22. Said release bar is provided at its forward edge with an -upturned or vertical, marginal flange 25 which has bearing contact with a rotative ring or roller 26 mounted on the escape wheel shaft 13 above the gear pinion 12. vWhen said release bar 19 is in its retracted position, the.

pinion 12 remains inl engagement with the ratchet teeth on the carriage frame, but when said release bar is thrown forward the pinion is forced outwardly or forwardly far enough to disengage it from the said ratchet teeth.

and thereby release the lcarriage from the escape mechanism, by which. letter space movement thereof is controlled.

So far as described, the parts are constructed in the same mannerjas in the Oliver U't ewritinO machines as heretofore constructed.

The front frame member or rack-bar '8 of'- the paper-carriage is provided with a depending, longitudinal ange 27, lwhichprefer-l ably extends the entire length thereof. Said flange is provided at its lower edge with a plurality of notches and preferably bears on its front face a scale, marked to correspondv with the letter-space movements of the carriage. Mounted on said flange 27 are adjustable stop-members 28. Each of said stop-members, as clearly seen in Fig. 6, consists of a metal block provided in its upperv part .with a notch to receive the flange 27 and having at its lower part an upwardly extending tooth 31 adapted for engagement with the notches on the lower edge of the said flange. In the particular form of the stopmember shown, the same consists of two parallel separated plates 29 and 3() joined by a transverse connecting part on the upper edge of which is formed the tooth 31. rlhe plate 29 is located in contact with the f rant face of the flange 27 and is provided near its upper edge with a stud 32 which projects rearwardly therefrom and is adapted to engage a'longitudinal groove 33 formed in the front face of the flange 27. The plate 30 engages the rear face o f the flange 2.7 and is .provided with a spring arma which projects upwardly and toward the left and is adapted to bear at its free end upwardly against the lower surface of the rack-bar 8. 'l'he stud 82 is located at a distance toward the left from the tooth 31, so that the up? ward pressure of `the free end of the springarm 34 against the rack-bar 8 tends to turn or rotate the stop-member about the stud32 in a direction to lift the tooth 31 or hold the same in engagement with one of the'notches in the lower edge of the flange 27 To shift or move the stop-member on the ange 27 its right hand end is drawn downwardly to release the tooth 31. from the notch engaged thereby and the stop-member is then slid 34, thrown upwardly to bring the said tooth into engagement withanother notch of the flange.

35 indicates a'key-actuated stop on the.

shift frame, which is movable vertically thereon to bring it into and out of the path of the stop-members 28 on the carriage. Said stop 35 is attached to the rear or inner-end of y a level' 36, arranged to extend from front to rear of the machine or at right angles to the )ath of the carriage and pivoted to the bracket 17 of the shift-frame, vpreferably at the right hand side thereof. Said leverl 36 is shown as mounted o n a pivot-rod 37 which is inserted horizontally `through the bracket 17' and rejects' beyond the right hand face of said lira-cker to forni a journal or bearing for the said lever. At this forward end, the lever 36 is provided with two rigid arms 38 and 39 arranged at an angle to each other. The arm 38 constitutes a forward extension of said lever and the arm 39 projects upwardly from the pivotal axis thereof. Said arm 39 4is adapted for contact at its rear edge with a stud 40, which rejects from theright'hand face of the. bracket 17 and constitutes'a stop to limit the downward movement of the inner or rear end of the lever. A sto 'is provided to limit the upward swing of tie lever 36 when the stop-member 35 is in its elevated position, or in the path of the stop-members 28; said stop, as shown in the drawings, consisting of a block 52, attached'to and proccting from the right-hand face of the racket 17, and against the lower surface of which 'the said lever 36 is ada ted to bear when the said lever 36 is in its ellevated position.

41 is a key-lever mounted on the bracket 17 so as to swing on an axis concentric with the ivot of the lever 36 and projecting forward) from said bracket. Said key-lever is conveniently mounted on the pivot-rod 37 at the left-hand side of the lever 36; its rear 4end being inserted in a vertical slot formed in the bracket to receive the same. Said keylever is Urovided at its outer cnd with a key 42 by which it may be operated. Said keylcver is provided with a stud 43 which projects from the right-hand face lthereof' in position to engage the under side or lower edge of the arm 38 on the lever'36. Said key-lever 41 is connected with the upwardly ex-l tending arm 39 of the lever 36 by means of a contractile coiled spring 44' connected at one end with said arm 39 and at its opposite end with th'e key-lever at a point forward of said arm. The sp1-mg 1s conveniently `connectentwith the key-lever by means of a stud-'t5 affixed to and projecting from the right-hand side of said key-lever. Said spring 44 tends to draw the upper end of the arm 39 forward and to hold the arm 38 in. contact with' the stud 43 on the key-lever. Said key-lever 41 is provided with a lifting spring by which its front end is hold normally elevated; said lifting spring, as shown in the drawings, consistingv of a contractile coiled spring 51 which is connected at one end with the stud 45 and at its other end with the bracket 17 (Fig. 2). The key-lever 41 is provided at its rear or pivoted end with an upwardly extending, rigid arm 46, the. upper end of which is connected. with a horizontally arranged connecting bar 47, through the medium of which motion is transmitted from the key-lever to the release bar 19 of the paper-carriage. Said plate 17, as clearly seen in Fig. 1, is arranged above thelevel of the gear pinion 12 and the said release bar 19 and at its rear end is provided with a downwardly extending ver, tical lug or iiange 48 which hooks over andv4 bears againsty the inner or rear face of the front marginal longitudinal flange 25 on the release bar 19. rl"l1e said bar 47 is provided with an aperture 53 through which passes a screw-stud 54 which is inserted into the upper end of the shaft 13 and serves to retain thereon. the ring or collar 26. The said aperture 53 is made larger t-han the stud54'so as to permit a slight relative movement. between the connecting bar and the said shaft. 'l'he upwardly extending` arm 46 of the keylever 41 is connected with said bar 47 in a manner to afford lost motion between said arm and bar, the parts for this purpose being constructed as follows: The bar 46 is provided at its forward end with a longitudinal slot 49 through which the upper-'end of the arm 46 of the key-lever upwardly projects; the front and rear edges of the arm 46 being adapted for contact with the opposite ends of 4the slot 49, which is made long enough to af- "below the bar 47, with a transverse pin 50 which serves to support the outer end of the bar.

The key-levler 41 is held normally in its elevated position by the spring 51; the upward movement of the outer end of said keylever under the action of said spring being limited by contact of the rear edge of the arm 46 with the forward end of the bracket 17. In the normal or elevated position of said key-lever 41, the upper end of its arm 46 stands in a position intermediate between the ends of the slot 49 inthe connecting bar 47 (Fig` 5), so as to leave said bar 47 free to be moved'forwardly with the upper end of the escape-wheel shaft 13 when the latter is swung forwardly to disengage the pinion 12 from the carriage rack in the usual o )eration of the carriage release devices. W ien said key-lever 41 is depressed bydownward pressure of the finger on the key 42, the lever 36 and the stop-member thereon are swung or ,moved with the key-lever to lift the stopmembel: into the path 'of the stop-members 28, 28, on the'carriage, such movement of the lever 36 with the key-lever'el resulting from so arranged with respect tothe outer end of the slot 49 in the connecting bar 47 that the key-lever will be moved downwardly far enough to bring the stop-member 35 to its elevated or"`carriage arresting position before the arm 46 comes into contact with the outer end of said slot 49 in' the connectinglbar.

When, in the downward movement of theA key-lever 41, its arm 46, in .the forward movement of the latter, strikes the outer end of said slot e9 inthe bare?, the said bar will be drawn or shifted outwardly or forwardly by the action of the key-lever, and the said bar, by its engagement of its hooked inner end with the flange of the release bar 19, will draw the latter forward and said release bar, by its action on the roller 26, will draw forward the upper end of the shaft 13, thereby releasing the pinion l2 from the carriage rack-bar and leaving the, carriage free to travel or move toward the left until its movement is arrested by contact' ofone of the stops 28 with the stop-member 35. The downward movement ofthe key-lever may continue'until the carriage release .bar 19 reaches the forward limit-of its movement, when further downward movement of said Akey-lever will be arrested. f

A typewriting machine equipped with column-stop or tabulating mechanism such as is above described may be operated for ordinary Writing in the usual manner without interference by reason of the presence of said mechanism. When it is desired to d'0 Itabulating work `or to Write a series of items or numbers in one or more columns on a sheet, one or more of the stop-members 28 are applied to the carriage and located atthe rcqu'iredposition or positions thereon according to the desired lateral location on the sheet of the column or columns to be written. Then upon-depressing the key-lever'4l, the carriage will be released and run to the position determined by the first or left-hand column stop, when the desired item may be printed inthe column. When -the .rinting of that item is completed, the keyever 41 may again be depressed and the carriage will be released and allowed to run freely to the may be released and stopped in position for printing a third or any other number of columns on the sheet.
